Command Line Switches

When creating a desktop shortcut for running Lianja Apps there are several command line options that can be specified.

The following table provides details of the currently available command line options. These can be combined to customize the running of an App e.g.

lianja --app orderprocessing --maximized
lianja myprogram.prg
lianjaruntime --kiosk --fullscreen --runtimecaption "Our company Apps"

Lianja Command Line Options

Option	Arguments	Description
--app	yourappname	Run the specified App.
--args	Arg,arg,arg	Specify an App specific comma separated list of args to be passed to a runtime script (see filename below). Enclose args in "..." and use single quotes for character args e.g. --args "'hello','world',2600,{04/04/1953}"
filename	None	A filename to run. If no file extension is specified it is assumed to be an App and .lianja is postfixed to it.
--fontsize	fontsize	Adjust the base fontsize of the App if you are using very high resolution displays and the default font size if too big or too small.
--fullscreen	None	Run the App fullscreen.
--geometry	x,y,width,height	Specify the geometry of the window.
--icon	Window icon	Specify an App specific window icon at runtime.

--noguests	None	Prevents readonly access to the Apps using the guest/guest login (disables guest login).
--password	Password	Specify a password for automatic login.
--reset	None	Run Lianja App Builder without restoring previous App state. Use this if something messed up in the App Builder and it won't load.
--runtime	None	Runs the Lianja App Center.
--runtimecaption	Caption text	Replaces the "Lianja App Center" caption text in the App Center Home workspace with the specified caption text.
--runtimedir	Runtime directory	Root directory where Runtime Apps, Library and Data are located, e.g. F:\Lianja\ or /opt/lianja/cloudserver/tenants/public/. This is the equivalent of setting the LIANJA_RUNTIMEDIR environment variable.
--splashscreen	Path to a custom splashscreen or "None" to disable	Specify an App specific splashscreen at runtime. Note that if --app is specified no splashscreen is displayed unless specified.
--title	Window title	Specify an App specific window title at runtime.
--username	Username	Specify a username for automatic login.

To run a custom program specify a file extension of ".prg" or ".dbo". (.dbo files are pre-compiled .prg files). Remember to add READ EVENTS at the end of the program file otherwise it will just exit and no UI will be displayed.

Note: If you are running some custom program code that is going to take a long time to complete e.g. consolidating inventory, then you can provide feedback to the user via a system tray icon on the desktop e.g.

tray = createObject("SystemTrayIcon")
tray.icon = "app:/myapp.png"
tray.showMessage("Message", "Consolidating inventory...")
// perform some long running operation to consolidate inventory
tray.showMessage("Message", "Consolidation completed...")
